PURPOSE:To prevent the generation of induced trouble in the electric circuit generating from the inside trouble of a rotor physical elements measuring device by a method wherein a current limiting resistor is inserted between the measuring terminal of the rotor physical elements measuring device and the electric circuit. CONSTITUTION:Measuring terminals 2a of a rotary part S of a rotor physical elements measuring device 2 are connected to the terminals of a rotary field winding 3 through a current limiting resistor 8. The rotary part S transmits the measured value to a stationary part R through a transmitting antenna 2b and a receiving antenna 2f. By this way, although short-circuit takes place in the inner circuit of the rotary part S of the rotor physical elements measuring device 2, because the high impedance is inserted between the terminals of the rotary field winding 3, so that the short-circuit condition does not occur. |
